Behind the colorful graphics and intense gameplay of every successful arena battler lies a complex, invisible mathematical engine.
This article explores how developers design these algorithms to keep queue times short while maintaining a competitive environment.
The Elo System Adapted
Most modern strategy games utilize a modified version of the Elo rating system, originally designed for professional chess.
This is why winning streaks inevitably end in a ‘wall’ of difficult matches; the system is functioning exactly as intended.
- The algorithm does not care what deck you are playing.
- Accept the RNG.
- In the lower arenas, the system often includes ‘bots’.
The Free-to-Play Dilemma
The standard Elo system works perfectly for chess because all pieces are equal, but tower rush games feature upgradeable cards.
To combat this, developers have implemented secondary checks that look at the player’s King Tower level.
| Conspiracy Theory | The Truth |
|---|---|
| Rigged Matchmaking | The algorithm does not force losses; you are simply playing tilted against harder opponents because your MMR is inflated |
| Rigged Deck Matching | Developers have confirmed repeatedly that the algorithm does not read the contents of your deck when finding an opponent |
True Fairness
This is why all true esports tournaments and competitive challenges utilize the ‘Tournament Standard’ ruleset.
When levels are equalized, the matchmaking system shines, ensuring that the better player almost always wins.
